Introduction to SOA

Section 1: SOA Concept

SOA Concept

SOA Features SOA is for Composite Business Applications SOA is a movement from monolithic to matrix Reuse and Remix are the key recipes and all other characteristics support this in

some form or fashion Black-box component architecture hiding complexity wherever possible

SOA is an architecture style that

creates reusable network accessible,

interoperable services, using vendor neutral

standards

Web Services – Technology that Powers SOA

Based on loosely coupled architecture, which increases adaptability to changing requirements

Independent of the implementation language and environment

Use widely known and accepted web standards: WSDL – Web Services Definition Language SOAP – Simple Object Access Protocol UDDI – Universal Description, Discovery and

Integration

Service Broker

Service Provider

Service Requester

WSDL WSDL

UDDI

SOAP

Web services are self-contained and self-describing software components that expose application functionality that can be processed through open internet standards

Web Services Standards

SOAP is a simple XML-based protocol to let applications exchange information over HTTP. SOAP stands for Simple Object Access Protocol SOAP is designed to communicate via Internet SOAP is platform independent and is a W3C Standard

WSDL is an XML-based language for describing Web services and how to access them. WSDL stands for Web Services Description Language Captures the “Service contract” between the service provider and consumer

– What operations does the service contain– How to invoke the operations (what url?)– What data to send and what to expect in return

W3C Standard

UDDI is an XML based language for registering and discovering services UDDI powers service reuse

We start by thinking about a new user centric process

reusing functionality of existing systems

Services Services ServicesService Enablement

The Systems have to be service enabled to provide

there functionality in a unified way

Exchange Infrastructure(optional)

XI/PI acts as the messaging middleware for service

communication, connectivity,

transformation and portability

The unified business object model provides the flexibility to make transparent usage of business objects with

local or remote persistency.

Unified services model provides service

abstraction and shields higher layers from

service implementation details making them
